Fixing a leaky PVC pipe is quite simple and involves searching for the source of the leak and using rubber sleeves and fiberglass tape to seal off the leak. Leaks can run up utility bills and cause physical damage to the surrounding structures; fixing the leak as soon as possible will help keep the damage minimal and avoid costly repairs.Continue Reading
The following steps show one method fixing a leaky PVC pipe.
Search thoroughly for signs of leaks. Mark the areas where the leaks are spotted.
After marking the area or areas where the leaks are, turn off the main water supply line.
Turn on the taps to relieve the remaining water pressure in the pipes. Make sure to completely drain the remaining water in the pipes.
Neoprene couplers, which look like rubber sleeves, can be used to seal off a leaky pipe. Often used as a device to secure two pipe joints, the rubber sleeves are held in place either by a C-clamp or a stainless steel hose clamp. If these devices are available, use them on the leaking area on the pipe.
Alternatively, a fiberglass tape may also be used to seal a leaky portion of the pipe. However, make sure that the pipe is dry when taping up the section and allow for the tape to settle into the pipe for 10 minutes before turning on the water supply again.
PVC glue can be used on CPVC pipe but doing so will often result in leaks and degradation of the seal on the joints, so it is not recommended. PVC and CPVC are made up of similar chemical elements, but they are not interchangeable.Full Answer >
To determine the correct size of PVC pipe for a project, use a pipe size chart to determine the pipe size that fits the supply line. The size chart can be used on the pipe that is being replaced, or can be matched at a home improvement store.Full Answer >
To cut PVC pipe, mark the measurement on the pipe, using masking tape as a guide, secure the pipe so that it won't move, then cut carefully along the marked line with a hacksaw or pipe cutting tool. This process takes about 10 minutes and requires a PVC pipe, masking tape, a measuring tape, a pencil, a miter box, and a hacksaw or pipe cutter. Wear protective eye wear and a dust mask to prevent injury.Full Answer >
To read a PVC pipe dimension chart, first identify the pipe schedule, which refers to the thickness of the pipe wall. Choose a nominal pipe thickness, or general size classification, from the far left column. Read to the right to find the pipe specs. The specs appear at the top of each column. PVC pipe dimension carts usually specify the outside diameter, the average inside diameter and the minimum wall thickness.Full Answer >
